I have been playing piano for practically my whole life, but I do not know any pieces. Is this normal?

I have been introduced to piano since I was a baby and started taking lessons at age 4. I'm now a teenager, but I still do not know any full pieces. All my friends who have been playing for less time than me know a lot more too. I feel like something is wrong and I'm wondering what other people think of this. Any advice is welcome as well!

PS: this is my first time posting here so I hope I did it correctly
